IMPROVEMENT IN ROPE OR LINE CARRYING PROJECTILES.

Specification forming part of Letters Patent No. 192,670, dated July 3,1877; application led May 28. 1877.

' To all whom it may concern:

-tral section, of my improved line-carrying projectile.

Similar letters of reference indicate corresponding parts. 4

The object of this invention is to furnish, for the purpose ofestablishing connection with the upper stories of burning buildings,

an improved line or rope projectile or conveying device, that is shot,in the nature ot' the line-carrying balls or rockets in coast-wreck--ing apparatus, from a gun or other imple' ment, to carry a line to theendangered persons, and admit the hoisting of a hose., rope-ladder, orother lireescape. The device may also be employed as 'a safety device onboard ot' vessels to convey the line ashore.

The invention consists ofl a hollow dart or projectile, with closed endsand a longitudinal slot for guiding the interior slide-piece, to whichthe life-saving string is attached.

In the drawing, A represents the arrow or projectile, that is made of ahollow tube of the size of the bore ofthe gun or other device from whichthe arrow is to be thrown. The tube A is closed at the ends, and made ofa diameter to t tightly into the barrel of the gun, so as to giveaccuracy in aiming and When the arrow A is placed into the gun, theslide-piece is at the upper end of the slot, and outside of the muzzleof the gun, the string being coiled in any suitable manner on theground. On 'firing the gun the s1idepiece is carried back tothe bottomend of the tion for hoisting ahose or any suitable iire escape availableatthe moment.

The slide-piece and string are arranged outside of the gun when the sameis fixed, so as to prevent any possibility of 'injuring the string bythe discharge of the gun.

By this means the upper stories of burning buildings may be brought, inan instant, in connection with the ground, the device form-V ing, in thehands ot' the fireman or others, a very simple and effective device forputting a lire-escape within the reach of persons in parts of buildingsthat cannot be reached in any other manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A line or rope projectile, consisting of a slottedtubular dart or missile, to be shot out of a gun or other device, andprovided with closed ends, and with an interior slide-piece and stringattached thereto, the whole arranged and operated substantially in theman-v ner set forth.
